I will be cutting over to Office365 from On-Prem Exchange 2007. I would like to run 2 Power shell commands / scripts to monitor the incoming traffic so I know when the DNS MX record change took.
the idea is to have one session monitoring our current server and another on O356. I will then see in real time the messages being redirected.
Is there any such command / script?
I know with mail assassin you can see real time messages coming in. But I can't find anything for Exchange.
Thanks,
